MEANS FOR STARTING INTERNAL-COMBUSTION ENGINES.

Application filed April 21, 1919. Serial No. 291,496.

To all whom it may concern:

Be it known that 1 CHARLES H. D. HAY- WARD, a citizen of the United States, and a resident of Newark, in the county of Essex and State of New'Jerse 'have invented new and useful Improvements in Means for Starting Internal-Combustion Engines; of which the following is a specification. This invention relates to meansb which an internal combustion engine provid ed with a storage battery and electric starter can be-started and said means afterward "returned to initial position by the running of the engine, as by the current generated by the engine, and while I have illustrated the invention applied'to a piece'of motor fire apparatus automatically started by a fire alarin, it will be understood that it canibe applied tom-any otheri artieular uses.

The o'bjects of the iriventio'n are to provide means forclosing a'eircuit from the storage battery to actuate the" starter which closing means shall} be automatically held closed by the current in 'saideircuit; 'to make saidclo'sing' means ndrihally open' so that it will return to initial po'si tiqnas 50th as the circuit is broken to thus require only closing of theclosing meansjby' the open atqr', and to obviate" the-necessity {or holding th'eclo's'ingimeans closed and'paying any attention to the time it 1 remains closed; or to theopening then-riff; to enable said-time 'of closure and openin'g'to be automatically de; termined by the running of the engin when started to utilize for such-closing means an electromagnetic switch in circuit with the storage battery; to use for such switch an eleotroinagn'et ,with an, armature which closes "theeirou it through the magnet; to

provide nieans by which the engine can be" operated independent of said closing ineans, and to obtain' other results "and advantages as may he out'by'the "following de scripti'on;

Referring to the accompanying drawing, thesingle figure thereof is 'a diagrammatic representation of a portion Oraam alarm circuit combined vyithltfie circuits are piece of a fire a pa atus ceerdin wy invention, and}: believedtosutfi'mentlj illustrate the same.

p In said drawing, the reference numerals l and 2 designate'th'e wires of a fineala'rin circuit, one of said wires as 2 being shown passing through fire alarm boxes 3, 3, any number of which may be employed and lo cated as is usual. That portion of my invention' which is attached to the firehouse or stationary is shown in the upper part of the drawing and the electrical circuits of the 'apparatus are shown in the lower part of the drawing, a separable connection cousisting-of members i, fi'bein provided for connecting sllCll circuits while the apparatus stands in the firehouse. This separableconneotion may be of any well-kiiown type, the member fi'bein'g fast t'o the fire apparatus and the'other' member 4 attached to thefir'e house,so' that they pull apart or separate automatically asthe apparatus goes out.

Thestationary portion of my invention, or portion whieh 'is attached tothe'fire house consists'bf'an electromagnet 6 inserted inthe wire or conductor 2 so that it is energized by the passage ofa current through 'the alarm circ'uit, it being understood that sucheireu its are 'commcntly of theiclosed' time and ope'n' intermittently to sound the" alarm. The' electro nagnet- 6 nor mally 'attracts the armature 7, pivoted as at8, 'and"holds it against the power; of an adjustable 'sprin'g' 9'rto'op'en a circuit closer 10 between; terminals 11, 12,o'ne of which is connectedfby circuit wi1es 13,=' 14' and 15 withbnebihdihig 'st of a'n= eleot ron1agnet 16 while the other terminal is connectedby circuit'wi'res 1 7,18,- '19, 2'0, 21 and 22*with oneterminal 'of the separable connection member-4', the"otherter niinal of said separable connection" being connected-bfwires 23-, 2 and 25 to the other binding post of theelectromagnet' 16;} 1 11 this way when the electromagneth releases its'arInatu reW," so that its circuit-closer"10 engages both terminals 11, 12, the electromagnet 16'isplaoed in a circuit from" the storage battery on the fire apparatus and is'iene'rgizedtherefrom.

Said magnet 16 then attracts its armature- 26, pivoted as at 27, and swings it a ain'st the power'o'f an adjustable spring 28, away from an' adjustable stop 29, to engage cir- 'cu it closerfif) with termiiials -3L,"'32,= which engagement will 'be oontinuous.

In order to cut out the device of my invention from th'e' fi're alarm circuit; when desired, a cut-out switch 36 is.providcd be tween adjacent'portions of the wire 2 on opposite sides of the electromagnet-(i, and up thermore to enable the current through said eleetron agiot (Bio-he. broken .whenever desired to testim-y improved-device, aitest key 37 is; also.- inserted. between. said adjacentportions of tllfWllC-Z.

In caseit is-desired at any time to operatetho machine manually by, actuation; of the foot operable switch 64 the SWitClLlBVBI; 73 must of-course stand-open on inneutral position, and so Ihave provided a. switch .74; between the wires. 68 and 69.:

for saidoircnit closer 65; by closing, this the ignition can becontrolled by the lever 73', asusual, andihy opening it and throwing said lever onto thebattery, theengine maybe started, by, the. automatic control.

The apparatus isprov-ided with a. genorator. as, is usualin motor vehicles. and whileithasbeen deemed unnecessary to. illustrate the same, I haveshown the circuit wires leading therefrom to. the storf age battery, one being, marked. with refer-emu: figures 75,. 76, 77. and the This having;

other with reference figures 78, 79, 80 i and,81.. Intoone. of these circuits, asbetween the wires-78-and;79,.is. inserted;an electromagnet- 82,.and,thus as :the generator. is .started. running, by the starting of: the motor said; electromagnetswings an armai ture. 83 itoiactuatea circuit breaker 84 her tween the. wires 45 andAG which lead from the. separable connection member 5 to the storage battery, said circuitbreaker being held by an adjustable-spring85in engage: ment. with its terminals 86,.87 while the generator is-idle, By thisumeans thestorage battery circuit throu h. the electromagnet 47 is broken and the armature 48 released to.-disengage. the circuit closer 52 from its terminals to stop :the starter 60 as soon asthe motor is running. Since this also disengages the circuit closer 65 and brealcsthe ignition circuit, it is necessary-to provide some means-for. lceepin nthe latter closed, which I have illustrated a circuit.

closer 88---on the same armature. 83 with the.

circuit: breaker. 84- andfladapted. to be engagedwith its.-terniinals 89,.90- as the cirr cuit breaker 84 is disengaged fromits terr ininals 8G, 87. Oneof these.terrninals,.as,90, is. grounded. to the frame. by. a. wire 91,

and the other terminal 89 is connected by wires 92 93 to the wire 70 coming from the storage battery, and thus asthe starter is automatically stopped, the ignition circuit is not disturbed.

It will be noted that the circuit breaker in thus breaking the starter circuit, also breaks the circuit through the separable connection members 4, 5 and releases the armature 26 of the armature magnet 16 forming a part of the stationary device or portion attached to the firehouse, so that said armature returns to initial position and all parts of that portion of the apparatus arev ready to operate again as has been described. The apparatus goes out of the fire house, separating the connection members 4, 5,and obviously upon its return when themotor is stopped the circuit breaker 84 returns to its position as shown in the drawing,so that when the connection members 4, 5 are again joined all parts of the entire device are in initial position as shown in thef'drawing and ready to operate again as has been described.

By my invention Ithus provide means forstarting the motor of the fire apparatus so' 'as' toLhaYe'said. apparatus all ready to go outftlie ins tant the firemen reach 1t, and alsof' lprovide means for atmy time testing all electrical circu'its both of my device and of the piece of fire apparatus. Furthermorefall this is donefrom through the fire alarm circuit and in such a way as to be autb'rnatic'and not interfere with the ordin'a "j'i'ise of said 'fire alarm circuit. Many mo ification's may be made in the detail arrangement 'of'the circuits and other parts invention, in constructing it, and l .d dj i bt w ish to be'junderstood" as limiting myself-e'xceptas required by the following claimswhen constri'ied ,thelight of the p'rior artli'i r f ;Haviii'g thus described the ingentiomwhat lk e mi s;
